General description

Chemical structure: fluoroquinolone
Norfloxacin is a broad spectrum antibiotic, which is used against a wide variety of gram positive and gram negative bacteria.

Application

Norfloxacin may be used as a standard in the determination of norfloxacin in human serum samples using fluorometric spectrophotometry.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Packaging

1, 5 g in poly bottle

Biochem/physiol Actions

Norfloxacin blocks DNA replication by interfering with an ATP-induced structural transition of DNA complexed with DNA gyrase (topoisomerase).
Mode of action: inhibits bacterial DNA replication
Antimicrobial spectrum: Gram-negative bacteria; less effective against Gram-positive bacteria

Fluoroquinolone resistance in members of the Enterobacteriaceae family is mostly due to mutations in the quinolone resistance-determining regions of the topoisomerase genes. However, transferable genes encoding quinolone resistance have recently been described. The current methods for susceptibility testing are not...

In the present study, we have synthesized 2-(substituted phenyl)-1H-imidazole (1-12) and (substituted phenyl)-[2-(substituted phenyl)-imidazol-1-yl]-methanone (13-26) analogues and screened them for their antimicrobial activity against gram positive, gram negative and fungal species. The results of antibacterial study indicated that compounds 15...

Intubated patients frequently become colonized by Pseudomonas aeruginosa, which is subsequently responsible for ventilator-associated pneumonia. This pathogen readily acquires resistance against available antimicrobials. Depending on the resistance mechanism selected for, resistance might either be lost or persist after removal of...

Fluoroquinolones are some of the most prescribed antibiotics in the United States. Previously, we and others showed that the fluoroquinolones exhibit a class effect with regard to the CLSI-established breakpoints for resistance, such that decreased susceptibility (i.e., an increased MIC)...
Articles
Quinolones are a key group of antibiotics that interfere with DNA synthesis by inhibiting topoisomerase, most frequently topoisomerase II (DNA gyrase), an enzyme involved in DNA replication.
